maximum http request in a page

How many http request does a browser can handle in a single html page. Their is a popular saying that browser can handle only a certain http request from a single domain and so its better to create static domain(cdn). so that http request can be shared between the 2 domains.

q1)How many http request can a browser handle in a single html page or atleast the saturation point(say 1000 requests)?

q2)How many http request from a single domain name can a browser render(say 100 from the same domain name)?

also any suggestions for best practices!!!

In theory there is no limit. But as the number of requests required to construct a page grows, the time taken for the page to be rendered increases. The relationship is not linear at low counts. Typically latency has a far bigger effect than bandwidth on actual throughput and there are mechanisms in HTTP to minimise the effect of this - such as keepalives and parallel requests. As Jon Grant says, there are limits on the number of concurrent requests.

A full answer to this question would fill a book - here's a good one.

Section 8.1.4 of the HTTP/1.1 RFC says a "single-user client SHOULD NOT maintain more than 2 connections with any server or proxy."

However, the key word is "should"; most browsers use a different number. See this blog for a table of max connections per browser.
